From the official Twitter:
A pretty uneventful opening 15 minutes, with neither side registering an effort on goal. Tuanzebe has assumed a holding midfield role in front of De Laet, Elphick, Bree and Taylor. El Ghazi, Adomah and RHM operating as a front three.
So even they are so confused they are forgotten Lansbury and Hourihane, presumably in front of Tuanzebe. So 4-1-2-3?
